Explanation:
The best way to separate the mixture is by using a bar magnet. We explore the magnetic property of the iron fillings in the mixture to separate it out.
- The mixture is spread out thinly on a flat surface.
- A bar magnet is hovered above the spread of the mixture
- The magnet attracts the iron fillings to itself
- This will leave the salt behind in the mixture.
The required temperature of the sample of gas is 823K.
<h3>What is ideal gas equation?</h3>
Ideal gas equation gives idea about the behavior of gas at different condition & represented as:
PV = nRT, where
- P = pressure = 500 torr = 0.657 atm
- V = volume = 5.01 L
- R = universal gas constant = 0.082 L.atm / K.mol
- T = temperature = ?
- n = moles
Moles will be calculated as:
n = W/M, where
- W = given mass
- M = molar mass
Moles of Neon gas = 1g / 20.1g/mol = 0.049 mole
On putting all these values in the above equation, we get
T = (0.657)(5.01) / (0.049)(0.082) = 822.8 = 823 K
Hence required temperature of the sample is 823 K.

Cu(s) + 2 AgNO3 = Cu(NO3)2 + 2 Ag 63.5 g Cu ---------------- 2 x 169.87 g AgNO3 ( mass Cu ?) -------------- 4.00 g AgNO3 mass Cu = 4.00 x 63.5 / 2 x 169.87 mass Cu = 254 / 339.74 = 0.747 g of Cu
